CHARLES F. SPENCER, OF ROCHESTER, NEV YORK.

CARPET-FASTENER.

Specification of Letters Patent No. 23,319, dated March 22, 1859.

To all whom it may concern.'

Be it known that I, CHARLES F. SPENCER, of Rochester, Monroe county, and State of New York, have invented a new Mode of Fastening Carpets; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawing, and to the let-ters of reference marked thereon, wherein- A, represents one of said fasteners of full size and B, represents the salne as driven into the floor, D, for use.

The forni is triangular', having an elongated point or shank b for entering the floor, a` sharp curved one (Z serving as a hook to catch into the carpet, and a plane a at right angles with the shank to enable itto be driven into the Wood. It is driven into the floor With the point l directed toward the baseboard or Wall, and a convenient distance therefrom, to enable the edge or hein ot the carpetto be passed between the hook and the Wall Gr.l A slight pull on the carpet causes it to be pierced by the point. (Z, and drawn down upon the ioor by the inclination of the hook. They should be inserted in the floor at proper distances apart, and. so deep that the head, or plane, a is sunk into the Wood even with the floor surface, so that it Will not Wear through, or he felt in treading upon it. For thick carpets it may be necessary to drive it into the fioor in an inclined position so as to raise the point higher, and for this purpose it may be varied so as to forni an angle more or less acute with the face of the floor D, according to the necessary elevation or depression of the point (l, the strain of the carpet holding itsecurely in its place.

The carpet can be readily and expedr tiously put down by catching it over the points of each, and even more readily taken up by simply raising the edge until it slips olf the points, rendering it very convenient for hasty removal in case of fire, &c.

These fastenings when once inserted never require to be taken up, and are remarkably durable and cheap. being cut -froln sheet metal by lneans of dies at a cost no greater than that of tacks.

That I claim as my invention, and desire to secure by Letters Patent, is-

A carpet fastener made of a single piece ot plate metal, of triangular, or three-p0int ed forni. one point serving as the shank to be driven into the Hoor, another point Z as the hook for receiving the carpet, and the third point a as a hea-d so shaped as to ena-ble the. fastener to be driven with facility into the floor, all substantially as herein Specified.

CHARLES F. SPENCER.
